Facebook is evolving its live video feature, and as part of the process, its testing auto-play video in users’ feeds with sound.
Right now, videos auto play in Facebook timelines and users must opt to hear sound by clicking on the volume button on the video. With this feature, the action won’t be necessary.
Mashable explained how the feature will work during the testing phase:
In one version of the test, sound plays immediately as the video begins, if you have sound enabled on your device. Another group is able to turn sound on during the test session using an icon that will sit to the bottom right of videos.
So, it won’t be as invasive as some people may fear. There will be plenty of opportunities to opt out, and it may be as simple as keeping your phone on the vibrate function.
